What Range of Motion Actually Means
Flexibility and mobility are not the same thing. Here is the difference, and why it matters for how you train.
Flexibility is how far a joint can be moved. Mobility is how far you can move it yourself, with control. The gap between the two is where most of the useful work happens.
Passive vs. active
If someone can push your leg higher than you can lift it, you have passive range you can't yet use. Training mobility means slowly closing that gap: teaching your nervous system that the end of the range is a safe place to be.
What to do with this
Spend time at the edges of your range. Move slowly. Breathe. Come back tomorrow. Progress is quiet and cumulative.
